Effect of ginseng extract on production of plasma proinflammatory cytokines (A), blood pressure-related factors (B), and the plasma LPC-generating enzyme activities (C). Plasma Angiotensin (ANG) II, lipoprotein-associated phospholipase A2 (Lp-PLA2) and lecithin cholesterol acyltransferase (LCAT) were determined using enzyme-linked immunosorbent assay (ELISA) kits. Plasma inflammatory cytokines including IFN-γ, IL-1β, IL-6, and TNF-α were measured using a luminex screen assay kit. Angiotensin-converting enzyme (ACE) inhibitory activity of ginseng and plasma ACE activity were measured at 228 nm by a spectrophotometer. Different letters on the bars indicate d significant differences at p < 0.05.
